Summary:  Memory corruption with STK500 and small memory sizes.

Original Submission:  The stk500.c fn's use paged mode on small memory devices 
e.g. eeprom on smaller devices. This causes memory corruption as paged read 
reads 256/128 bytes in mem->buf which could be as small as 64 bytes.



This can be fixed by reducing the page size to the actual size of the 
read/write (stk500 handles internals itself).



I have a hack that proves this approach works without problems, unfortunately 
not suitable for a patch as it's too messy!
